Electric motor for actuation of windows and mirrors in vehicles, has carrier ring section for press seat, with second adjacent section having internal diameter greater than shaft's outer diameter for accommodating ring magnet

摘要

The motor has a magnet body (24) mounted on a rotor shaft (12) to detect rotations and revolution rate, with a carrier ring (26) seated on a press seat on the shaft, and a multi-pole annular magnet (27) held by the carrier ring. The carrier ring has a first section (261) for the press seat and a second ring section (262) adjacent to the first, in the axial direction, with an internal diameter greater then the shaft's outer diameter for accommodating the annular magnet.
